xhoWhat is a CO2 Laser? Complete Guide for Industrial and Medical Use
A CO2 laser is a high-power infrared laser that uses carbon dioxide gas as the medium to produce a concentrated light beam. It’s one of the most widely used gas lasers in the world, especially popular in medical procedures, industrial cutting, and engraving applications due to its efficiency, precision, and versatility.
Understanding the CO2 Laser Technology
What is a CO2 Laser and How Does It Work?
A CO2 laser generates light by electrically stimulating a gas mixture that includes carbon dioxide, nitrogen, and helium. This process produces infrared light with a wavelength of 10.6 micrometers, which is particularly well-absorbed by organic materials such as wood, leather, acrylic, and human skin.
Core Components of a CO2 Laser System
The basic components include:
Laser tube – where the gas is excited to generate laser.
High voltage power supply – delivers the required energy.
Cooling system – usually water-based to prevent overheating.
Focusing optics – lenses and mirrors to direct the beam.
Types of CO2 Lasers: Sealed vs. Flowing Gas Systems
Sealed CO2 lasers are maintenance-free and commonly used in medical and small industrial applications.
Flowing gas CO2 lasers offer higher power for heavy-duty industrial use but require more maintenance.
